UBUNTU-CVE-2026-46145

In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Validate rxhashkeylen Sashiko points out that rxhashkeylen comes from a uAPI structure and is blindly passed to memcpy, allowing the userspace to trash kernel memory. Bounds check it so the memcpy cannot overflow...

CVE-2026-46220

The CVE affects the Linux kernel AMDGPU SDMA4 path. In sdma_v4_0_ring_emit_fence, two BUG_ON(addr & 0x3) checks caused a fatal kernel panic when reachable from unprivileged userspace via DRM_IOCTL_AMDGPU_CS submissions. The fix replaces BUG_ON with WARN_ON to log misalignment without crashing; mi...

CVE-2026-45962

A flaw was found in the Linux kernel's userspace block ublk driver. This vulnerability allows a local attacker to cause an out-of-boundary memory access by providing a specially crafted command that bypasses the IOURINGFSQE128 flag check. This could lead to a system crash, resulting in a denial o...

CVE-2026-45975

A flaw was found in the Linux kernel's ublk subsystem. A local attacker could exploit a race condition where the kernel reads struct ublksrvctrlcmd from userspace-mapped memory without proper synchronization. This allows a malicious user to concurrently write to the structure, potentially causing...
